After listening to the Jupiter-80 again I have to say I'm very impressed. One issue keeping people from liking it is the lack of sampling. I think Roland's reasoning is that the Supernatural sounds take place of any multisampling or single shots of everyday instruments. They went to a lot of trouble to program these sounds in a way that is not static like a sample, but flowing and dynamic. Also, If you are making your own sounds from complete scratch with all layers this machine is capable of, its going to be ridiculous to get into single shot or multi samples. I'm sure the idea is to build off what they have already provided for you. Compared to something like the V-synth GT or V-synth factory presets I think they've got better presets on the Jupiter-80. After listening to more demos, I think they have given you more than enough to start tweaking useful sounds.
One other thing to note was the possibility of layering an arpeggiator with other sounds. You can play a pad with a chord and automatically have a different arpeggiator cycling in the "background". I'm not sure what other roland equipment does this, but its very powerful. It sounds like you are playing an entire song with a few keys. The amount of layering on the Jupiter-80 can save a lot of time and sound very good.
The other problem Roland has on their hands is all the comments from analog purists. Jupiter-80 obviously is digital and getting a lot hate because it isn't like the Jupiter-8. It is still meant to be their top of the line keyboard. This is probably the most advanced keyboard they've ever made, lacking sequencer. From one perspective, the Jupiter-80 can sound much better than what the Jupiter-8 does. If you want your music to stay in the past, get something thats been available for 30 years. If you want to go to the future get the Jupiter-80.
Things I like on Jupiter-80:
- Layered Sounds + Arpeggiator.
- Super Natural Sounds & rom take place of sampling (save time)
- Color Scheme
- Sheer Power
